Eyeliner with automatic liquid discharge device

The present invention relates to an eyeliner, and more particularly to an eyeliner with an automatic liquid discharge device that allows the air flow path and the liquid flow path to be separated independently and has a stable and smooth liquid discharge effect.

Referring to FIG. 1 , the conventional eyeliner 10 mainly includes a casing 11 , a regulating valve 12 , an ink cartridge 13 , a cotton refill 14 , a fixing base 15 and a brush tip 16 , and the ink cartridge 13 is connected. It is disposed at the rear end of the air regulating valve 12, and is internally filled with a cosmetic liquid. The air regulating valve 12 is internally provided with a shaft hole 121 for the cotton refill 14 to be inserted, and the rear end of the cotton refill 14 extends to The ink cartridge 13 absorbs the ink, and the outer portion of the air conditioning valve 12 is provided with a plurality of blades 122. One side of the blades 122 penetrates into the shaft hole 121, so that the ink absorbed by the cotton refill 14 can be permeable to the ink. The blade 122 is stored and adjusted for water volume. The fixing seat 15 is sleeved at the front end of the air conditioning valve 12, and an outer side is provided with at least one opening 151. An air flow path 152 is formed between the outer periphery of the fixing seat 15 and the air regulating valve 12, and the air flow path 152 is formed. The air flow passage 152 is communicated to the brush tip 16 by the opening 151, passes through the cotton refill 14, and finally reaches the blade 122 of the air regulating valve 12, and the brush tip 16 is disposed inside the fixing seat 15 and protrudes at the front end. Extending out of the outer side of the fixing seat 15, the rear end of which is connected with the cotton refill 14, the cotton refill 14 After sucking the ink, it can be discharged through the front end of the brush tip 16.

Although the above-described eyeliner 10 has an automatic liquid discharge effect, there is still a need for improvement in use. In the course of use, the conventional eyeliner 10 passes through the cotton refill 14 to reach the brush tip 16 for discharge. When the regulating valve 12 generates a negative pressure inside, the outside air enters through the air flow passage 152. After the air passes through the cotton refill 14, it finally reaches the blade 122 of the regulating valve 12, thereby balancing the internal pressure. However, the conventional eyeliner 10 allows air and ink liquid to flow together in the same channel, and the two form a confluence at the cotton refill 14, and the flow of air and the outflow of the ink often interfere with each other, causing the brush tip 16 to discharge. In an unstable state, when the blade 122 of the damper valve 12 accumulates too much water, the ink easily oozes out along the path of the flow path 152 to the opening 151, causing water leakage.

Therefore, the present invention aims to provide an eyeliner with an automatic liquid discharge device that allows the air flow path and the liquid flow path to be separately branched.

Therefore, the present invention provides an eyeliner with an automatic liquid discharge device, the eyeliner comprising a tube, an ink cartridge installed in the pen tube and containing cosmetic ink, the back end of the automatic liquid discharge device and the ink cartridge In connection, the front end protrudes from the outside of the pen tube for discharging ink, and comprises a head sleeve, a fixing seat, a regulating valve, a cotton refill and a brush tip, wherein: the pen head sleeve is mounted The fixing seat is sleeved at the front end of the pen sleeve, and at least an air inlet is defined in the outer portion of the pen holder. The outer circumference of the fixing seat is recessed with a ventilation channel at a position corresponding to the air inlet; the air regulating valve is installed It is arranged in the sleeve of the pen, and has a shaft hole penetrating inside, and the outer part is provided There are a plurality of blades, and the outer periphery of the blades is cut at one side with a slit penetrating into the shaft hole, and the blade at the front of the valve body is further provided with a notch communicating with the venting channel of the fixed seat, and the air is conditioned. A first end portion of the valve is inserted into the front end of the valve, and a second end portion of the ink cartridge is inserted into the rear end of the air regulating valve; the cotton refill is disposed in the shaft hole of the air regulating valve The back end of the brush extends to the ink cartridge to pick up the ink; the brush tip is disposed inside the fixing seat, the rear end of the brush pen is connected with the front end of the cotton refill, and the front end protrudes outside the fixing seat; by the combination of the above structures, The path from the ink cartridge, the cotton refill to the tip of the brush defines a liquid flow path for the ink to be discharged, from the air inlet of the fixed seat, the venting channel, the notch of the regulating valve, the blade, the shaft hole to The path of the ink cartridge defines an air flow path through which the air flows, and the air through the air flow path can enter the ink cartridge to maintain the balance of the internal gas-liquid pressure.

The utility model has the beneficial effects that the air flow and the liquid flow path which are separated independently are used, so that the flow action of the air and the ink does not interfere with each other, thereby achieving the effect of smooth and stable liquid discharge.

Can be in contact with the human body.

The above is an overview of the shape of the eyeliner member with the automatic liquid discharge device; then, the action of the present invention and the expected effect can be stated as follows: Referring to FIG. 10, the present invention consists of an ink cartridge 22 and a cotton pen. The path of the core 60 to the brush tip 70 defines a liquid flow path (I) for the ink to be discharged. When the user uses the present invention for makeup, the ink liquid in the ink cartridge 22 is sucked by the cotton refill 60. Thereafter, the liquid flow path (I) is routed to the front end brush tip 70 for liquid discharge.

Referring to Figure 11, the air inlet 43 of the fixed seat 40, The venting channel 44 passes through the notch 515 of the damper valve 50, the vane 513, the slit 514, the shaft hole 512, the vent hole 531, and finally reaches the path of the ink cartridge 22 to define an air flow passage for air circulation (II) When the ink is discharged through the brush tip 70, the amount of liquid contained in the ink cartridge 22 is reduced to generate a negative pressure inside, and the outside air enters through the air inlet 43 of the fixing seat 40, through the air flow passage (II). The route reaches the ink cartridge 22, thereby allowing the internal gas-liquid pressure to be balanced, so that the ink can smoothly and stably perform the liquid discharge operation.

In summary, the eyeliner with the automatic liquid discharge device is mainly for improving the mutual interference of air and liquid in the internal eyeliner 10, and the technical means used in the present invention is the original liquid. In addition to the flow path (I), an air flow path (II) separated from the liquid flow path (I) is additionally designed. The air flow path (II) of the present invention starts from the air inlet 43 of the fixed seat 40. The air venting valve 50 is introduced through the venting channel 44, passes through the blade 513 of the tempering valve 50, and finally reaches the ink sump 22, thereby balancing the internal gas-liquid pressure. Thus, the present invention utilizes the air flow passage (II). The design of the liquid flow channel (I) is provided separately, so that the air and the ink have independent channel paths and do not interfere with each other, thereby the present invention has a smooth and stable liquid discharge effect, and because the air flow channel (II) and the liquid The flow path (I) is disposed separately, and the ink does not enter the air flow path (II), so that the present invention does not cause water leakage.

However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto, that is, the simple equivalent change of the patent application scope and the patent specification content of the present invention is Modifications are still within the scope of this new patent.
